Title: Production of ammonium sulphate
IPC: C01C1/248
Filed: 1938-06-08
Abstract: 511,390. Ammonium sulphate. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. June 8, 1938, No. 17030. Convention date, June 9, 1937. [Class 1 (ii)] In the production of ammonium sulphate by the reaction of sulphuric acid with ammonia, coarse-grained crystals are obtained by adjusting the amounts of sulphuric acid to maintain a concentration of free acid not exceeding about 3 per cent., and by carrying out the crystallization in the presence of sufficient pentavalent arsenic, and if desired phosphoric acid or a phosphate, to ensure the precipitation of iron, aluminium, chromium and like impurities. Any deficiency in pentavalent arsenic may be made up by an addition of pentavalent arsenic or by the conversion of part or all of any trivalent arsenic present into pentavaent arsenic. It is unnecessary to separate the precipitated impurities before the crystallization. Specification 423,397 is referred to. The Specification as open to inspection under Sect. 91 describes also the use of a sulphuric acid prepared with a specially high arsenic content and to the addition of iron in the process. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,126,979. 1,3,5-Triazine derivatives. CIBA Ltd. 19 April, 1966 [20 April, 1965], No. 17174/66. Heading C2C. [Also in Division C3] The invention comprises compounds of the formula where R is a substituted or unsubstituted phenyl ring, which may be fused with another 6- or 5- membered aromatic ring, and which contains a hydroxyl group in a position ortho to the bond through a ring carbon with the triazine ring, Y and X are different and represent -O-, -S-, or -NQ- (where Q is hydrogen or a C 1-4  alkyl group), and A or B each independently represent a group containing up to 20 carbon atoms selected from alkyl, alkenyl, cycloalkyl, aralkyl, phenyl and naphthyl, which groups may be substituted. Numerous compounds of the above formula are specified, including those in which the radicals R, A and/or B are substituted by halogen, hydroxy, alkoxy, carboxy, carbalkoxy, carbalkoxyalkyl, aryloxy, cyano, substituted carbamoyloxy and/or carbaryloxy groups. The compounds are made by reacting a cyanuric halide with (1) 1 mol compound H-X-A, (2) 1 mol compound H-Y-B and (3) with 1 mol compound R-H in the presence of a Friedel-Crafts catalyst in an anhydrous organic solvent. Steps (1) and (2) are generally effected in an aqueous medium in the presence of an acid acceptor, or, if X and Y are -S- or -O-, using the metal salts of H-X-A or H-Y-B. For step (3) the preferred catalyst is AlCl 3 . As a variation of the above process, further compounds can be prepared by exchange reactions between the residues -X-A and -Y-B to introduce different -X-A and -Y-B residues, e.g. by transetherification, or transamidation. The radicals R, A and B introduced by the above methods may be further modified, e.g. by reacting hydroxy substituted R, A or B radicals with organic halides, acylating agents or isocyanates to give ethers, esters or carbamates. The triazine compounds are used for stabilizing organic materials against the action of light, heat and oxygen (see Division C3). Numerous examples are provided.

Title: Reflex camera
IPC: G03B17/52
Filed: 1972-04-17
Abstract: 1351425 Operation of reflex camera POLAROID CORP 17 April 1972 [16 April 1971] 17605/72 Heading G2A  A single lens reflex camera is converted from a viewing mode to an exposure mode and back again by a motor-driven operator means, the two conversion movements being effected by successive energizations of the motor. Fig. 2 shows a folding reflex camera erected into the operative position, the base housing a cassette 54 containing a stack of film units, unit 56 uppermost. This is exposed through an opening 58 and subsequently ejected through a slot 62 for processing. The cassette also contains a flat battery below the film units. Fig. 2 shows the camera in its viewing mode, an assembly 66, having a mirror 68 on its upper surface, being pivoted to the camera body by hinges 72, 74. Light passes through the objective lens 110 to a mirror (112), Fig.4 (not shown) on the inside of the rear camera wall 44, thence to mirror 68 and upwards to a viewing assembly 114. During this operation the camera shutter is maintained at maximum aperture by an auxiliary dual-bladed section 122, 124 in front of a photo-cell exposure control assembly. These have tapered aperture openings, and are linked to opposite ends of a reciprocating beam 126. The beam is tensioned by a spring 140 so as to maintain the shutter at its maximum aperture. During a photographic cycle, an actuator button 446 is pressed to energize a solenoid 142. This causes beam 126 to pivot and so close the shutter. The conversion of the camera from the viewing to the exposure mode is effected by a brief energization of a motor 150, which mechanically releases the assembly 66 and allows it to be pivoted upwards by springs 84, 86 into the position of Fig.4 (not shown), in which light entering the lens 110 is now reflected downwards by a mirror 70 on the underside of assembly 66 on to the uppermost film unit 56. Solenoid 142 is now de-energized, so that spring 140 causes the shutter to open, and the sections 122, 124 to admit an increasing amount of light to the photo-cell assembly. After an appropriate amount of light has been admitted, solenoid 142 is again energized to close the shutter. Motor 150 is again energized, which actuates the mechanism restoring assembly 66 to the viewing mode, and moves unit 56 out through slot 62 to the processing rollers 158, 160. Solenoid 142 is now de-energized once more to open the shutter. Finally, motor 150 is de-energized, which shuts down the electrical control system, this being set out generally in Fig. 8 (not shown).
